To all whom, it may concern.-

The principle of emptying flushing-tanks about equal to the sectional area of the siby siphons has long been in use; but before Be it known that l, ISAAC SHONE, asubject my invention in tanks so emptied it has been of the Queen of Great Britain, a resident at found very often the case that when the tank 55 Great George Street Chambers, Parliament fills slowly and evenly without agitation the 5 Square, London, England, have invented new contents are apt to dribble over the bend or and useful Improvements in Flushing-Tanks, lip of t-he si phon and thus destroy the flush- (for which I have obtained a patent in Great ing properties.

phoii-pipe d each time it overbalances. The capacity of the vessel 7i. is such that when the tank-body a is charged with liquid thel next discharge of the tumbling vessel 71, into the pipe a will suddenly raise the level of the liquid in the pipe a and the short leg cl2 of the Siphon d in excess of the capacity of the bend or lip of the Siphon d, and so cause the siphon to discharge the contents of the tank a full bore into the drain i.

Figs. 2 and 3 Show a flush-tank, also designed as a house-sewage flush-tank, but made of cast-iron and in one piece, and provided with a cover a2 to the body ct. The sewageinlet or Soil-pipe I), the ventilatingpipe c, the funnel supply-pipe a', and the short leg cl2 of the sipho'n discharge-pipe d, all pass through this cover a2, which is also provided with a man-hole and cover a3, through which access can be had to the tank ci.. The sewage- 'inlet pipe b, the funnel-pipe a', and the short leg d2 of the Siphon d are all brought nearly to the bottom of the tank a, and the two latter are trapped by the liquid in the tank, which is made deeper at one end for this pur- The tunnel-pipe a is provided with a spherical head aiwithin which the tumbling vessel h is hung on tru unions 7L', as shown in dotted lines. The tumbling vessel 7L is fed by a small stream direct froma water-service pipe a5, or by Sink, lavatory, or bath wastes through the pipe e. Thetank a is filled with house-Sewage through the soil-pipe l). The water-supply from the pipe ci or lavatorywastes from the pipee ow into the tumbling vessel h in the funnel-pipe a', and when the vessel h is filled it suddenly cants over and discharges its contents into the -funnel-pipe a', (entering the tank a.) The effect of this action when the body a is charged with liquid is to Start the Siphon d into operation by suddenly illing its bend d. The Siphon d continues its action until the tank is emptied, when the entrance of air into its shortleg stops its working. The flush-tank o acts also as a perfect trap between the liouse and the drain or Sewer i, and is ventilated by the pipe c. Its use in connection with house-drainage will be apparent by reference to. Fig. 3. in this figure there is shown the connection of the tank a with a gravitating Sewer m in the Street. It will be seen that the liouse-drain 'L' connects with tributary drains t" and leads to a ventilated nian-holel and then joins the St'reet-sewerm. In this case the supply to the tumbling vessel 47L may be by a water- `service through the pipe a5, or troni the Sinkslops and lavatory or bath wastes through the pipe e. It desired, the tumbling vessel h may be fed solely by the water-Service pipe a5, and the sink-slops taken direct to the housedrain through the pipe e. The adoption of the flushing-tank a in connection with housedrainage confers advantages that cannot be overestimated, inasmuch as it utilizes the sewage proper 0f the house as ameans of cleansing and keeping clean the pipe leading to the street-sewer.

Figs. 4 and show a [lush-tank, with the siplion discharge-pipe d. and funnel-shaped pipe a and tumbling basin 7L provided. outside the tank-bod y d. The tank a is fed with water or other liquid or Sewage through the pipe l). The tumbling vesselh is supplied with water by means of the Service-pipe a", and comes into action only when the tank a is filled to the required level. The supply is opened and closed by a valve orcock a", which is actuated by a oat. This oat is placed in the tank a at the level to which the liquid is to rise in it before it is flushed out. This float and valve or cock may be of any known kind, which, when raised by the rise of level of lthe water in a tank, opens a valve, and when such level falls closes it. Between the funnel-pipe a and the tank a there is anonreturn valve p, which prevents the liquid from the funnel-pipe a entering the tankbody d when the tumbling basin h tips over. Thus the Siphon d iS sure to fill and start fullbore and continue until the contents of the tank oy are discharged, and the tank can be discharged at any level by settin g the Iioatvalve to act at that level.

The detail of the valve a7 and its float is Shown in Fig. G. As before stated, the valve a7 is placed in the tank with its float as on a float-lever set at the level to which the liquid is to rise in the tank before it is Iiushed ont. The auxiliary Water-service pipe a will in practice connect with a water-main, and is used to charge the tumbling basin h when the liquid in the tank a has reached the level at which it is to be discharged. The valve a7 is brought into action by the float as being lifted. Then the liquid in the tank a reaches the level at which the float as is set, then the valve a7 opens by the rising of the iioat as and iioatlever, the water flows through the pipe a5 and charges the tumbling basin 7i, which, when full, tips over, and thus Starts the Siphon d. As the liquid in the tank ais discharged, the oat as and float-lever falland close the valve ai, which remains closed until the tank a is again filled.

An apparatus constructed according to my invention can be used with great advantage for flushing sewers or drains at their heads or sources. The apparatus may be supplied with liquid by a branch from the sewer itself or with water from a inain or otherwise, which water may be slowly running into the iiushtank, which when full Will flush the Sewer 0r drain. The iiow of water may be so arranged as to tlush the Sewer or drain a given number of times during the day or other period of time. Thus a constant automatic Iiushing ot the sewer or drain is obtained, which can be applied to any gravitating or other system of Sewerage.

I do not broadly claim the combination of a tilting tank with a Siphon which is charged IOO IIC

and brought into action by the tilting of the tank when full. My invention involves a novel construction and combination ol dcvices for improving the ei'iiciency of this type of ushing-tanks- It will be observed that according' to my invention l provide an internal supply-pipe having an enlarged head and a lower portion of contracted area, the contracted area extending above the bend of the Siphon, whereby the siphon is sure to start on the least tip of the tumbling vessel when the tank is full. 'lhe cubic capacity of the tumbling vessel is greater than that of the top bend of the Siphon at the other end of the tank, and whenever the latter has been llilled up to the level of the inside of the siphonbend any more sewage entering the tank from the contributary sewers will of course fall down the longer leg ot' the siphon and find its way to the sewer at the same rate as it enters t-he tank; but at the next oversetting of the `tumbling .box a head of water is momentarily raised in the contracted area of the supply-pipe, which is sufficient to fill thenpper bend ol' the siphon and inevitably set the latter in continuous action until the whole tankful of sewage has been discharged at the high velocity beginning with that due to the height of the upper end of the filled tank above its point of exitinto the sewer requiring to be flushed.

In my invention it will be seen that means are provided for lillingor charging the tank independently of the tumbling vessel, andl that the tumbling vessel is only used to start the Siphon; and, further, my flushing-tank is arranged for ushing sewers, and, through the contracted supply-pipe, is positive in ac- `tion.

The water-tap may be so adjusted as to afford the impulse necessary to discharge the dashing-tank as frequently or as seldom as may be required with the smallest possible expenditure of clean water from thestreetmain, and all the benefits of periodical {lushing` may thus be obtained by means of only a very small percentage of the clean water, which is often wasted in order to attain this object.

l. rlhe combination, with a flushing-tank, a discharge-Siphon therefor, and a tumbling vessel, of a supplypipe comprising an enlarged head located above the highest part of the siphon and a lower portion ot' contracted area extending downward from the enlarged head, substantially as described.

2. The combination of a flushing-tank, a discharge-Siphon, a tumbling vessel, a service-pipe for the tumbling Vessel, an independent service-pipe for charging' the tank, and a supply-pipe comprising an enlarged head located above the highest part of the siphon, and a lower portion of contracted area extending downward from the enlarged head, substantially as described.
